Wedge clamp for adjustably affixing a support bracket to a weaving machine

Abstract

An apparatus for adjustably affixing a support bracket to a part of a machine frame includes an adjustment screw to adjust the height of the support bracket on the frame and a pair of oppositely movable clamp elements having oblique surfaces for wedging the support bracket in place following adjustment. Wedging is accomplished by turning a setting screw to move the clamp elements in mutually opposite directions. The setting screw is parallel to the adjustment screw, allowing equal access to both the adjustment and setting screws.

I claim: 
     
       1. In an apparatus for adjustably affixing a support bracket to a machine frame, comprising means including an adjustment screw for adjusting a position of the support bracket, and means for fixing the support bracket in the adjusted position to the machine frame, the improvement comprising: a guide having an undercut groove and a guide fitting provided between the support bracket and the machine frame part, wherein said fixing means includes at least one clamp element and means including a setting component mounted between the support bracket and the machine frame for driving the clamp element in order to press the guide fitting against a surface of the groove.   
     
     
       2. Apparatus as claimed in claim 1, wherein the setting component for the clamp element is mounted parallel to the adjustment screw. 
     
     
       3. Apparatus as claimed in claim 1, wherein the position of the support bracket is adjustable by said adjustment screw in an adjustment direction, and the clamp element is a wedge clamp arranged to be driven by the setting component in said adjustment direction. 
     
     
       4. Apparatus as claimed in claim 1, wherein the clamp element is a wedge clamp element mounted between an end face of the machine-frame and the support bracket, said clamp element comprising one surface which is parallel to the end face and one wedge surface which faces an oblique surface of the support bracket. 
     
     
       5. Apparatus as claimed in claim 4, further comprising a second mutually opposite wedge clamp element, said clamp elements being arranged to be driven in a mutually opposite directions by the setting component. 
     
     
       6. Apparatus as claimed in claim 5, further comprising stop means on the support bracket for limiting a distance by which the clamp elements are be driven in mutually opposite directions by the setting component. 
     
     
       7. Apparatus as claimed in claim 5, wherein the setting component is a setting screw arranged to allow mutual tightening of the two clamp elements. 
     
     
       8. Apparatus as claimed in claim 7, wherein the setting screw is threaded into a thread of the first clamp and comprises a driver rigidly joined to, said driver being arranged to engage the second clamp element and thereby drive it. 
     
     
       9. Apparatus as claimed in claim 8, wherein the support bracket is arranged to support a warp deflecting roller in a weaving machine, the support bracket being mounted to a lateral part of the machine frame.
